What is the reason for the rough idle when starting a cold GL8?
1 Answers
GL8 rough idle when starting cold reasons: 1. Uneven working conditions of each cylinder: After prolonged use, the spark plugs in the car can cause the gap during ignition to become uneven, which reduces the power of the cylinders in the engine. This leads to unstable idle, shaking, and vibration during cold starts. We can replace the spark plugs to fix this issue. Long-term use of the engine can also cause the distance between each cylinder liner and piston to become uneven, reducing the car's power during startup and resulting in unstable idle. 2. Low engine temperature: This situation is very common in winter. During a cold start, the temperature of the car's internal parts is similar to the outside temperature. At this time, ignition can cause unstable idle and body shaking due to the engine's low temperature and insufficient power. Therefore, in winter, we should try to park the vehicle in a garage, as the garage temperature is higher than outside, which can help alleviate the issue of vehicle shaking and unstable idle. 3. Incomplete combustion of gasoline: Incomplete combustion of gasoline during a cold start indicates insufficient engine power, leading to vehicle shaking. Therefore, after starting the vehicle, we should not rush to ignite it immediately. Instead, wait for a while to allow the engine to build up sufficient power, ensuring complete combustion of gasoline and preventing this issue from occurring.
